Process for the production of meat powder



"UNITED STATES PATENT OFFICE.

. WILLIAM EREDRICK REMTis, or RANG-ATAUA. AND ALEXANDER EDMUND MACREDIE AND CHARLES FREDERICK CORK, oEAUCKLAND', NEW zEALA-Nn- PROCESS FOR THE PRODUCTION OF MEAT POWDER.

No Drawing.

To all whomit may concern: Be it known that we, WILLIAM FREDRICK Beams, ALEXANDER EDMUND MAOREDIE, and CHARLES FREDERICK CORK, subjects ofthe King of Great Britain,.residing at Bangataua, Auckland, New Zealand, and Auckland, New Zealand, respectively, have invented a new and useful Improved Process for the Production of Meat Powder; and we do hereby declare the following to be a full, clear, and exact description of the same.

This invention relates to an improved process that has been devised for the production of meat powder from beef, mutton and the like, in a form suitable for packing and storage. These powders are then useful for the preparation of the foods such as jellies,

soups, etc, for which the ordinary meat ex-.

tracts are used.

The present process'consists in the sub mission of the meat to an initial slow drying operation, followed by a smoking or preserving treatment, and finally a grinding or powdering operation.

In carrying out the processthe carcass to be treated is hung unt1l it sets and all animal heat is evaporated. It is then boned and all superfluous fat removed, after which the meat is cut up into blocks of suitable size. For the best practical results. the blocks of meat should be about a thickness of three inches in diameter and of any desired lengths.

7' These blocks are then laid across shelf gratings or trays with grating bottoms and placed within a suitably constructed drying room in which a temperature of about 135 Fah. is maintained. The meat is subjected to the action of this heat for a period of not less than thirty-sixhours nor more than forty hours; during which time' the room is kept dry by carrying offby suitable mechanical agencies all steam or moist heat and moisture given off from the meat; Any

sweating or cooking of the meat is thereby prevented. 7

When this. drying process is completed? the shelves or trays, with the meat thereon,

are transferred to a smoke chamber conmaybe varied to suit special Specification of Letters Patent. Patented J 11119 28, 1921.

Application filed September 10, 1919. Serial No. 322,996.-

ing finally led to an outlet through which.

it is carried. off so as to also carry with it any moisture contents of the room. The meat is subjected to the action of the smoke for a period of eight hours.

After this period has clasped the meat is removed and it is then in a state or condition ready for breaking up or grinding into powder. The operation for thus breaking and grinding it may be performed by any convenient forms of known grinding mills and sieve it to the required degree of fineness. 1

The powder thus produced may then, af ter it has thoroughly cooled, and preferably not before the expiration of'aperiod of four hours, be packedinto suitable containers for the meat may be varied and adapted to suit different circumstances and therefore they form no features of the present invention. Care must be takenhowever, that in thelr construction, full provision is made for the uniform circulation of the heating and smoking agencies throughout the Whole 'area, so as to treat all the contents equally,

and also for the ready escape of all moisand the necessary degree of fineness, to pass through the sieve.

In all cases the, times of treatment and the temperature of the drying operation requlrements and the nature of the meat being operated on.

We claim: I A process for the production of meat powder consisting in the subjection of raw cold meat in blocks to the drying action of'a specification in the presence of two subscribmg witnesses.
